Explain abnormality through the Deviation fom the social norm.
Social norms are rules based on how society expects us to behave, any deviation from this is viewed as abnormal. Each society has its own set of norms and tehrefore we need to look as each society in order to identify and decide if an individual is either conformingoor deviating from the social norm. Therefore, much behaviour which appears normal in one context becomes abnormal if it appeas in another. E.g. its normal to remove your clothes when going in the shower, but is a different issue when removing your clothes in public.
